Basic System and Operation
Description
Note: This section applies only to tracked versions of the
machine.
Running Gear Components
The track assemblies are mounted on each side of the
machine chassis in place of the wheel hubs. Fig 1. (
X J-1)
shows the track mounted on the right hand side of the
machine, Fig 2. (X J-1) shows the separate running gear
components.
The machine sits on rollers A which run inside the rubber
track B. A front idler wheel C slides in grooves in the track
frame and locates against the spring loaded recoil unit D
which protects the track against shock loadings. A grease
filled hydraulic cylinder inside the recoil unit provides a
facility for the correct tensioning of the track. Rear idler
wheel E gives additional secure location for the track.

The track is rotated by a hydraulic motor F mounted on the
track frame. Sprocket G on the output shaft of the motor
locates in holes in the track.
